Kubuntu 14.04.2, Radeon HD5770.
When i am going on suspend mode(RAM) screen goes black and then PC might or might not go into this mode. Sometimes it just hangs on black screen part and thats it. It happened to me with all of the previous drivers(and mesa 10.1) but i've seen once back then so i thought its a rare bug.
Filled ram or not, i don't what may be the cause and where to look for errors to post here, so if you'll tell me where to look i'll post them.
